I ordered a tee fitting for the Window Washer on my 1990 740. When it
arrived I tried to blow through it in all directions but found it
wouldn't pass any air at all.
I contacted the supplier and they sent me another one. This one is the
same. If I can't blow through it how could a small pump force water
through it? Am I missing something or doing something wrong ?
Thanks,

On mine (1987 740) when I took it off and blew through it, there was a
one way valve inside of it. You should be able to pass water from the
bottom up and out through the two sides only.
My red top was leaking water, so I used some Automotive GOOP to seal it
and it worked fine for me. I'm not sure why it needs this valve. Maybe
to keep the pump primed, or to provide even pressure to both sides.
Try it with water on the car to be sure.

This is normal. The pump puts out much higher pressure than your
lungs. Install it and see.

Oh, if you want to see something fun, if you ever have to re-wire the
pump -- switch the wires on the two prongs. Mine reversed direction and
was sucking instead of pumping.
Weird.

They're just a permanent magnet DC motor driving a pump consisting of
two meshed gears. If you reverse the current, the motor will run
backwards and it'll pump in the opposite direction.

So you're saying I can make my Volvo suck?
LOL

That's why I named my XC70 Linda Lovelace.

You were right Mike, I put it on and, as I sat there amazed, the darn
water came right on through like magic.
Thanks all,

Those pumps are capable of much more pressure than your lungs, try it,
it'll probably work fine.

When I worked in an avionics shop that included an instrument shop, I tested
my lung power to see how much pressure I could produce by blowing. As an
avid cyclist at the time I thought I could blow a storm. 2 PSI was the best
I could manage!
